Abstract
Experimental results are presented for several exchange-coupled nanocrystal line alloys of composition Sm-18(Fe,Co)(82) with different Fe contents. Min or loops, Henkel plots, and recoil curves are shown to be in excellent agre ement with calculations performed using the moving Preisach model (MPM). Ex perimental reversible and irreversible magnetization components are found t o be in excellent agreement with MPM simulations. (C) 1999 Elsevier Science B.V. All rights reserved.
